Advanced quantum systems are integral to scientific research and modern technology enabling a wide range of emerging applications. Nitrogen vacancy (NV) centers, optically active atomic defects in diamond, are naturally relevant in this context due to their unprecedented spatial and field sensitivity, single-spin addressability, and remarkable functionality over a broad temperature range. Many of these advantages derive from the quantum-mechanical nature of NV centers that are endowed by excellent quantum coherence, controllable entanglement, and high fidelity of operations. In this talk, I will present our recent work on developing state-of-the-art NV-based quantum sensing and imaging techniques and demonstrate their direct applications to address the current challenges in both condensed matter physics and quantum sciences and technologies. Specifically, we have utilized NV centers to probe the exotic charge and spin properties of emergent quantum materials including high-Tc superconductors, magnetic topological materials, and antiferromagnetic insulators. We also integrate NV centers with functional magnetic devices to develop hybrid quantum systems, promoting the role of NV center at the forefront of quantum technologies. Lastly, I will briefly discuss our ongoing efforts to explore quantum sensing using emergent color centers beyond NV centers.
